Use the slope of the given line to construct a parallel line

Mathematics

Answer:

y = - \frac{4}{3} x - 7

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slope m of the given line using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = \frac{-2-2}{3-0} = - \frac{4}{3}, thus

y = - \frac{4}{3} x + c ← is the partial equation

To find c substitute P(- 3, - 3) into the partial equation

- 3 = 4 + c ⇒ c = - 3 - 4 = - 7

y = - \frac{4}{3} x - 7 ← equation of parallel line

Kamila [148]

Answer:

x = 2

Step-by-step explanation:

Since the triangles are similar then corresponding sides are in proportion, that is

\frac{AB}{DE} = \frac{BC}{EF} , substitute values

\frac{7x}{7} = \frac{4}{x} ( cross- multiply )

7x² = 28 ( divide both sides by 7 )

x² = 4 ( take square root of both sides )

x = \sqrt{4} = 2

What is the following product? 4 square root 7
Charra [1.4K]
The answer is: The product 4 \sqrt{7} is a radical multiplied by an integer and the result is 10.58
 By definition, the set of integers has: negative numbers, positive numbers and zero.
 Radicals are also known as roots and can be written with the symbol: \sqrt[n]{} 
 , where "n" is the index.
 Normally, when a radical is multiplied by an integer, you must simplify it, but in this case you can calculate the result by using your calculator.

Using the formula F=9/5C+32, find C when F= 75.
den301095 [7]

Answer:

DIVIDING 9 AND 5 = 23.8

9/5 FRACTION = 0.04

Step-by-step explanation:

If 9/5 means 9 divided by 5

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5 = 1.8

1.8C = 43

1.8C/1.8 = 4

If 9/5 means 9/5ths fraction

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5C / 9/5 = 43 / 9/5

C = 0.04

Hope this helps i thought 9/5 was 9 divide by 5. If it was 9/5 as a fraction i also made that equation too.
